Today, vacuum hardening is an indispensible part of a modern quality hardening shop. Vacuum technology meets the highest demands for surface quality and mechanical properties of your components. Changes in shape and dimensions (warping) are reduced to a minimum.


Vacuum technology is therefore particularly well suited for both premium precision tools and for demanding machine components with low machining allowances.


The continuous heat treatment in the vacuum creates finish qualities that are essential for PVD and CVD coatings.




- economic and environmentally friendly hardening process

- high process safety

- low dimensional changes and warping

- scale-free, metallically pure surface

- reproducible results
